Hello,
The issue has been raised a few times already on the list, IIRC.
Just a little reminder:
- Create dbHandling.h (class definition) and dbHandling.cpp (member function
implementations).
- If you are using sql_create_# macros, and you include dbHandling.h in
another file, you'll get linking conflicts (namely on ::_table and ::names).
To solve that issue, custom.pl needs a small modification so that it
generates a custom-macros.h which only defines ::_table and ::names once.
There is a small quick-n-dirty patch attached.
Apply with: patch -p0 < ssqls-link.patch
Then run: custom.pl
You'll now have a new custom-macros.h.
If you dont want the static members to be defined in a file, then just:
#define MYSQLPP_SSQLS_NO_STATICS
Don't forget that you need the static members to be defined at some point
(but only *once*).
Just a note: this has been tested only under Debian unstable/FC4. I have no
access to Windows development machines. Any feedback on different
architectures is welcome.
Hope some people will find this useful.
Viktor
